摘要： The leaves (200) of a multi-leaf collimator can be driven more easily and hence more quickly if they are supported on a ball-race (202) instead of in a sliding groove. A recirculating path is preferred, in which the rolling elements of the ball-race support the leaf over part of their path and then return to a start of the path. In addition, the rolling elements could be driven by a drive screw (206) in order to drive the leaf.

摘要： A fusion reactor includes an improved ability to modulate a plasma for specific purposes. The reactor operates on the ability to change at least four separate variables in each of a plurality of lenses that are independent of the other lenses. This allows for the generation of Alfvén waves and modulation of the internal plasma dynamics, actively leading to higher states of efficiency. By combining modulation of a plasma in the form of an ion beam with a solid state metal target, an efficient fast neutron source can be produced. This can lead to industrial applications such as energy generation, nuclear clean-up, the production of rare earth metals out of semi-rare ones, and helium production.

摘要： A control circuit 201 administers a radiation treatment plan that specifies a planned total radiation dose for a radiation treatment session for a given patient 207 by modulating a radiation beam 203 with at least one high-resolution aperture that is formed using one of a plurality of linearly-sequential high-resolution aperture possibilities. By one approach the foregoing comprises modulating the radiation beam using at least substantially only high-resolution apertures that are formed using a plurality of the linearly-sequential high-resolution aperture possibilities. In some cases the foregoing can comprise administering the radiation treatment plan using at least two separate radiation exposures for only a single treatment field, in which case, by one approach, each of the separate radiation exposures for the single treatment field can comprise modulating the radiation beam using at least substantially only high-resolution apertures.

摘要： A grid employs dynamic and adjustable grid lines that communicates with a transmitting object and/or a receiving object. The grid lines may be but not limited to liner, crosshatched or pinwheel shaped. The grid may switch between opaque and translucent and the grid lines may target, calibrate to and track an object either transmitting or receiving. The grid may be employed as a filter or a privacy screen on a computer screen for instance. The grid lines are angled to match an angle of a user's position with respect to the grid.

摘要： A system for subsea imaging comprises a first plate having an inner surface, an outer surface, and a cavity formed in the inner surface. In addition, the system comprises a phosphor imaging plate disposed in the cavity. Further, the system comprises a second plate having an inner surface facing the inner surface of the first plate and an outer surface facing away from the outer surface of the first plate. Still further, the system comprises a seal member disposed between the inner surface of the first plate and the inner surface of the second plate. The seal member extends around the perimeter of the cavity and is configured to seal the phosphor imaging plate and the cavity from intrusion water.

摘要： A multi-leaf collimator for radiation therapy in which the position of the leaves (10; 10 - 1...10 - 20) are determined by measuring a magnetic field allows determine the leaf position with enhanced precision, and is at the same time robust to perturbations or disturbances. The magnetic sensor (12, 14) may comprise a magnetic encoder (14) that varies in a predefined pattern along a lengthwise direction of the magnetic element (12), in particular according to step function.
